Brut Yellow Label (Methuselah) (6 L)

In 1816, Barbe-Nicole Clicquot Ponsardin — a 27-year-old widow with no legal right to run a business — invented the riddling table, the mechanical breakthrough that made mass-production of clear Champagne possible. Every bottle of Yellow Label that exists owes its clarity to that decision. The Methuselah format (6 L, equivalent to eight standard bottles) extends that legacy into a format where the surface-area-to-volume ratio slows micro-oxidation dramatically, deepening autolytic development on the same base wine. The blend is Pinot Noir-dominant (~50–55%), with Chardonnay (~28–33%) and Pinot Meunier (~15–20%), drawn from 50–60 crus — including Grand Cru villages Bouzy, Ambonnay, Verzy, Verzenay, Avize, and Le Mesnil-sur-Oger — with 25–50% reserve wines held up to 30 years in the house's 24 km of UNESCO-listed chalk crayères beneath Reims. Soils are shallow chalk on hillside slopes: maximum drainage, high reflectivity, and a cool subsoil that preserves acidity through ripening. Fermentation is in stainless steel (8–10 days); full malolactic fermentation is carried out across the range, a deliberate softening of the chalk-driven acidity that defines the house's generous, broad-shouldered style. A proportion of base wines see large oak foudres (since 2008) for textural layering. Minimum 30 months on lees — double the AOC floor — at a dosage of 9 g/L. The Methuselah is the special feature: large-format aging in bottle produces a measurably slower, more reductive autolytic arc, yielding deeper brioche and nuttier lees character than the standard 75 cl release of the identical base wine.
